I wasn't sure if computer equipment could withstand the cold environment in a barn and since my barn is metal, I wasn't sure if a bridge would even work. My camera comes with a removable antenna so I replaced it with a Yagi high gain antenna and mounted it outside. I was thinking of adding an antenna to the router too to see if I could get more bars.
Right now I have it aimed at the entrance to the barn but I need to hang it up higher to get a wider angle. I haven't seen a thing on my camera though. Not one possum, not a skunk. So I wonder what has scared them all off. I know that something attacked one possum , we found it bleeding in the grass and it died later. And I found another possum dead beside the barn fence.
